2018 Physical Review A  
We theoretically investigate mid-and long-wavelength infrared laser filamentation in solids, revealing extreme self-steepening and optical shock, multi-octave spanning supercontinuum generation, and most importantly sub-cycle light bullet generation. Light bullet generation in solids at long wavelengths depends critically on plasma, which is in sharp contrast to that in air where the arrest of collapse for light bullet generation is dominated by radiation loss. Our method for sub-cycle light
